19.5.1 and 19.5.2 break 4k @60hz 422, 420 support. I have to change refresh to 59hz to get 422,420 etc. I did a clean install on both new versions. Reverting back to 19.4.1 eliminates the problem. Have tried on 2 Tvs same results. One Samsung Q8 and LG C8 oled. 2 Different GPUS Radeon VII and Vega 64. Please fix this.
